Visopsys is an alternative operating system for PC compatible computers. This is a maintenance release, with numerous small improvements and bugfixes including some general back- porting from the 0.6 development branch. In addition, IDE disk-to-disk operations have been improved so that they can happen in parallel, the kernel hardware drivers have been given a new interrupt handing interface, and there is some improved efficiency in a performance-critical section of the multitasker.
